You can certainly replace the crown with a non-metal option like zirconia to get rid of the dark band. The dark tooth next to it is probably a separate issue.
The shape of your lips are very different from the pictures. It may be a very fine line between "accentuated" and "rabbit". Before doing anything, ask your dentist to do an experimental "mock up". If I were doing the case for you, I would take a mold and have my lab make the changes you are requesting on a model. Then, we would make a template to transfer the changes back to your teeth with bonding. The bonding is not actually glued - it is just locked in between the teeth temporarily. It is minimal cost and gives you the opportunity to try things on and make changes without commitment. If you are unable to get the look, pop them off and you haven't gotten a bunch of shots or wasted a bunch of time and money. If you live with them for a day or two (you have to be careful with them) and think they rock, you now have the exact plan for the finals by taking a mold of them. The ceramic artist will index and copy them for the new Emax restorations. Good luck on the journey!
First, congratulations on your new smile. It is a lot of work and I think they are a nice improvement! I would encourage you to wait a little before making any big changes. Your temps look like copies of your original teeth but whiter so they felt very "normal" to you. I agree that your final crowns/veneers have more curves but I think they look more feminine and more natural that way. If you look at the edges, they are actually really close to the same position. The face of the tooth simply has more contour and the edge is slightly longer and more rounded. Your canine was in crossbite before and now is built out with the veneer. That will take some getting used to. It could only have been avoided by doing a quick course of braces or invisalign to move the teeth into better position before the prosthetics were done. Without the orthodontics, this is a nice camouflage. Let your dentist know that you may want to come in to reshape the edges but that you will take some time to evaluate first. I have had many patients over the years that want to make changes because everything is so new but I have given them the same advice I have just given you. When I see them at their next recall, most have thanked me because after living with their new smile for just a couple of weeks, they decided that everything was great. If you decide that you want the edges reshaped and polished, it is not difficult at all. Just remember, we can always take away but once we have taken it away, it can't be added back!
Both situations are probably normal and you will just need some time (and maybe some advil or tylenol). Your teeth are held in by ligaments that act as "shock absorbers" when you bite. When we put a new crown in, we look to have really tight contacts between the teeth when we try it in. If they start out light, once the crown settles in, there will sometimes be gaps which will trap food and be really annoying! When they start out tight, once the crown settles, the contacts will be "normal". These tight contacts actually put some pressure on the adjacent teeth - only a fraction of a millimeter but enough to notice at first. Some people get sore but it will go away. If it is still sore after a couple weeks, ask your dentist to do a simple bite check. The second situation is likely referred pain. All of the nerves bundle together in what is called a ganglion before going to your brain. Like a big ball of electric wires all jumbled up. Because of this, your brain sometimes misinterprets any misfires as coming from other places. This is why it is hard sometimes to even figure out which tooth may be hurting when you have a toothache. I have seen so many patients that swear their pain is coming from a top tooth and when we test it is on the bottom! It is a perfectly normal phenomenon. Give it some time - we don't often think of going to the dentist as getting "surgery" but if you think about it, you really just had micro-surgery on these two areas and your body will need a period to heal.
It looks like you have plenty of gum tissue over the implant though it is hard to judge without seeing a radiograph. That is great - usually we have the opposite problem - not enough gum! I think there are two things that may be done to improve the look of your canine. First, if the lower tooth is in the way, see if your orthodontist would be willing to do a quick limited treatment to tip it back slightly so it is symmetrical with the other side. You could also consider reshaping the enamel if it is not far off and forego more braces. This will allow the top tooth to be longer without hitting. It is important that the bite be correct because implants do not "like" being hit side-to-side. On the top end, a little cosmetic gum shaping to expose more of the fake tooth will help lend the appearance that it is more alike than different. This may also give your restoring dentist enough room to change the angle and color of the crown to better match the other side. Best of luck - these impacted teeth cases are always difficult!
